This patchset adds more features support for FPGA Device Feature List
(DFL) drivers, including PR enhancement, virtualization support based
on PCIe SRIOV, private features to Port, private features to FME, and
enhancement to DFL framework. Please refer to details in below list.

This patchset is created on top of these patches from Alan.
[PATCH 0/4] patches for FPGA - https://lkml.org/lkml/2019/5/9/1002

Main changes from v2:
 - move thermal/power management private feature support to another
   patchset, including hwmon patches and related documentation update.
 - update sysfs doc for kernel version and date.
 - replace scnprintf to sprintf for sysfs interfaces.
 - fix comments for performance reporting support. (patch #16)

Main changes from v1:
 - split the clean up code in a separated patch (patch #2)
 - add cpu_feature_enabled check for AVX512 code (patch #4)
 - improve sysfs return values and also sysfs doc (patch #12 #17)
 - create a hwmon for thermal management sysfs interfaces (patch #15)
 - create a hwmon for power management sysfs interfaces (patch #16)
 - update docmentation according to above changes (patch #5)
 - improve sysfs doc for performance reporting support (patch #18)
